1	推行供應鏈管理之不確定性因素及其因應策略之研究－以台灣資訊電子業為例 / The Research on the Uncertainty Factors and Their Adaptive Strategies for the Implementation of Supply Chain Management --- Using Information & Electronic Industry in Taiwan as the Study Object 羅國正, Lo, Kou-Chein Unknown Date (has links) 供應鏈管理的實質利益來自於改善企業內與企業間整體供應鏈網路的作業流程，使其各個環節在成本、品質及效率上都能大大的改進，這驅使大型企業紛紛帶頭建立自己的供應鏈體系，並與過去視為敵對的上下游廠商共同合作，以獲得整體供應鏈的利益及優勢。在推行供應鏈管理的過程中，管理營運之不確定性的掌控良好與否為供應鏈管理推行成功與否的重要關鍵因素之一，因為不確定性因素會直接或間接影響企業的績效，造成企業有形或無形的損失；在這個變動快速且競爭激烈的時代，能夠降低不確定性的影響就能降低風險，才能獲得或維持競爭優勢，故針對國內企業特質提出一套不確定性因素的因應策略是有必要的。本研究透過文獻探討蒐集彙整一般企業在推行供應鏈管理時所面臨之不確定因素的來源及影響，接著，蒐集過去學者對於此一問題的解決方法，並提出一個初步的因應策略架構。在因應策略架構中，本研究使用圖形模式化工具來表達企業流程以輔助分析，並與相關規劃及作業人員討論，以找出所有不確定性因素的來源及不確定性因素的影響，對於不確定性因素的來源，採取盡量降低其發生的預防策略；對於不確定性的影響，採取盡量減少其傷害的應變策略。其次，本研究以台灣資訊電子業為例，進行個案研究以了解企業如何因應不確定性因素，並利用分析的結果來修正初步的因應策略架構，以符合台灣企業本身的現況，最後作綜合整理分析並提出建議，以作為將來台灣資訊電子業在推行供應鏈管理時相關策略的參考。 / The benefits of Supply Chain Management come from the improvement of the whole operation processes of the supply chain network. These make large enterprises build their supply chain network and cooperate with their up-stream suppliers and down-stream customers to produce a larger overall benefit. To be success in implementing supply chain management, there are many critical successful factors. Managing the impact of uncertainty in implementing the supply chain management is one of them, since uncertainty will directly or indirectly influence the performance of business operations and will cause tangible or intangible damages. In the era of rapid change and sheer competition, eliminating the impact of uncertainty will help company to reduce the risk and gain/sustain their competitive advantages. In this thesis we focus on the Taiwan enterprises’ characteristics, and propose adaptive strategies to manage the uncertainty. This thesis collected the sources and impacts of the various uncertainty factors based on the literature survey of previous studies, then we review the solutions, which was announced, and propose a prototype of the architecture of adaptive strategies for these uncertainty factors. In this architecture we use graphics modeling tools (IDEF0) to present business processes, then take a discussion with related planners and operators to find out all the sources of uncertainty and the impacts caused by the uncertainty to the company. For the sources of the uncertainty, we take possible preventive strategies to reduce the probability of occurrence. For the impacts of the uncertainty, we take possible defensive strategies to eliminate the impacts of the uncertainty. Then we use case study to understand that how Taiwan’s Information & Electronic companies do as they suffer from uncertainty and to correct the prototype of the architecture. Finally, we synthesize the discoveries, and provide the helpful suggestions to Information & Electronic Industry in Taiwan for a reference if they want to implement Supply Chain Management. 供應鏈管理不確定性因素資訊電子業 Supply Chain Management Uncertainty Factors Information & Electronic Industry
2	Development of Sensitive In Vitro Assays to Assess the Ocular Toxicity Potential of Chemicals and Ophthalmic Products McCanna, David January 2009 (has links) The utilization of in vitro tests with a tiered testing strategy for detection of mild ocular irritants can reduce the use of animals for testing, provide mechanistic data on toxic effects, and reduce the uncertainty associated with dose selection for clinical trials. The first section of this thesis describes how in vitro methods can be used to improve the prediction of the toxicity of chemicals and ophthalmic products. The proper utilization of in vitro methods can accurately predict toxic threshold levels and reduce animal use in product development. Sections two, three and four describe the development of new sensitive in vitro methods for predicting ocular toxicity. Maintaining the barrier function of the cornea is critical for the prevention of the penetration of infections microorganisms and irritating chemicals into the eye. Chapter 2 describes the development of a method for assessing the effects of chemicals on tight junctions using a human corneal epithelial and canine kidney epithelial cell line. In Chapter 3 a method that uses a primary organ culture for assessing single instillation and multiple instillation toxic effects is described. The ScanTox system was shown to be an ideal system to monitor the toxic effects over time as multiple readings can be taken of treated bovine lenses using the nondestructive method of assessing for the lens optical quality. Confirmations of toxic effects were made with the utilization of the viability dye alamarBlue. Chapter 4 describes the development of sensitive in vitro assays for detecting ocular toxicity by measuring the effects of chemicals on the mitochondrial integrity of bovine cornea, bovine lens epithelium and corneal epithelial cells, using fluorescent dyes. The goal of this research was to develop an in vitro test battery that can be used to accurately predict the ocular toxicity of new chemicals and ophthalmic formulations. By comparing the toxicity seen in vivo animals and humans with the toxicity response in these new in vitro methods, it was demonstrated that these in vitro methods can be utilized in a tiered testing strategy in the development of new chemicals and ophthalmic formulations. in vitro Alternative Methods alamarBlue rhodamine tight junctions bovine lens viability toxicity mitochondria mitochondria integrity benzalkonium chloride sodium dodecyl sulphate sodium lauryl sulfate scanning electron microscopy Draize Draize maximal average scores zonula occludens cosmetic directive PETA humane society animal league ICCVAM ECVAM JaCVAM BCOP bovine cornea ocular irritants ocular irritation ocular toxicity human corneal epithelial cells vitro confocal confocal microscopy metabolic activity optical quality reactive oxygen species contact lens contact lens care solutions barrier function microbial keratitis mulitipurpose solutions tight junction cell damage claudin ZO-1 occludin MDCK Madin Madin-Darby canine kidney cells cornea human cornea human corneal epithelium epithelial cell line human corneal epithelial cell line sodium fluorescein sodium fluorescein permeability fluorescein permeability ocular surface cell monolayer Araki-Sasaki cell physiology risk assessment safety assessment ScanTox scanning laser lens epithelium corneal cells in vitro model ophthalmic formulations multiple instillation back vertex animal testing rabbit testing alternatives to animal testing cultured bovine lens toxicity of chemicals irritation irritants laser scanner organ culture delayed toxicity toxins hydrogen peroxide cornea toxicity cornea toxicity models prediction of human toxicity no observable adverse effect level lowest observable adverse effect level NOAEL LOAEL toxicity thresholds safety factors cornea uncertainty factors preservatives disinfectants ophthalmic products preclinical preclinical testing epithelial barrier drug penetration clinical confocal microscopy animal rights rabbit cornea human cornea human clinical effects toxic animal rights activist sensitive measures toxic effect toxicity threshold agar overlay agar diffusion agar overlay method agar diffusion method cytochrome cytochrome c apoptosis necrotic apoptotic necrosis caspase rhodamine 123 resazuran resorufin cell death cell viability metabolic dye microsomal microsomal enzymes cytotoxicity cytotoxic cytotoxic effect MTT XTT WST-1 plasma membrane mitochondrial mitochondrial morphology ocular toxicity potential ocular toxicity human corneal epithelial cell line confocal analysis corneal epithelium cell fluorescence alamarBlue assay rhodamine dye animal welfare toxic injury degraded mitochondria epithelial monolayer disinfectants membrane integrity eye toxicity eye viability dye toxicity in humans human toxicity effects on the mitochondria mitochondrial toxicity in vitro battery in vitro test battery ophthalmic eye drop direct contact product safety cytotoxicity potential molecular molecular biology refine reduce replace sensitivity and relevance sensitivity relevance rabbit ocular irritation test product development cytotoxicity models cytotoxicity alternative methods replacements for animal testing three r's beagle tiered testing tiered testing strategy replacements animal testing mechanistic toxicity cornea mitochondria dose response threshold Vision Science and Biology
